Black hole scattering near the transition to plunge: Self-force and resummation of post-Minkowskian theory

Published in Physical Review D, 2024

In this paper we demonstrate how strong-field self-force information can be used to resum weak-field post-Minkowskian series for the scatter angle during hyperbolic encounters, significantly extending the latter's domain of validity.

Frequency-domain approach to self-force in hyperbolic scattering

Published in Physical Review D, 2023

In this paper we develop a frequency-domain code to calculate the scalar-field self-force along hyperbolic orbits in the Schwarzschild spacetime. Chosen as an Editors' Selection in Physical Review D and recipient of the 2023 STAG Research Center prize for best student publication in gravitational physics.
